nto useless channels of thought-force. Conscious attention
concentrates and even specializes mental energy as the sun-glass
concentrates and intensifies the heat of the rays of the sun. Focus your
full attention upon the thing to be done, take a keen interest in its
accomplishment to the exclusion of all else, and you will obtain
wonderful results. The man of developed, concentrative power holds in his
hand the key to success, with the results that all his actions, voluntary
or involuntary, are pointed to the accomplishment of his object. Remember
therefore in conclusion:

(1) Concentration is perfect attention consciously directed to a
given point of achievement either objectively or subjectively.

(2) Concentration is consecration.

"What ever you do, do it with all your might. Do one thing at a time and
do it well." By concentration is meant the directing of all your energies
along a special line of achievement. For instance, if you would be a
perfect Yogi, you must concentrate, concentrate, morning, noon and night,
at all times, along that line of endeavour. You must study all the vast
literature on Yoga, Psychology, Metaphysics, Mentalism, etc., and form
your own synthesis on same. You must think hard and work hard for Yoga.
"Genius is the power to bear infinite pain." Nothing ought to be too
great a sacrifice, including your own life, for the right understanding
and achievement of Yoga.

All half-heartedness, all insincerity, weakens your nature, and
weakness has no place either in heaven or in hell. For the half-hearted
man is a traitor unto the Divine within him and must pay dearly for
his treachery.

SUBJECTIVE CONCENTRATION--HOW PRACTISED.

This is a vast subject. If you practise earnestly my instructions on
Thought-Control, Will-Culture, and take the Meditation Exercise I am
going to give you, you will realize greater strength than average
humanity. But you must study and think hard for yourself before any
considerable benefit can be derived from even these. Remember please, you
alone can teach yourself through intuition. Intuition is tuition from
within. Follow strictly the general rules I give you and you cannot but
unfold your Inner Soul Vision which includes intuition in its fullest
sense.

_(a) What is Thought-Force?_

"Thoughts are things." Thought is a dynamic energy. Just as the food that
you eat feeds your body, exactly similarly your thoughts and feelings
nourish your soul. Matter is not
